I have just migrated from Ubuntu 11.04 to Linux Mint 11. As a consequence, I do not dare to claim that it is not possible with Linux Mint, but the feature has deliberately been discarded from Ubuntu 11.04. Because Linux Mint 11 is based on Ubuntu 11.04, it is likely that Mint does not offer that option anymore either.
There is a bug report on that topic in the Ubuntu Launchpad bug report site, but I do not remember which one. You should be able to easily find it. There was a fierce debate about that topic in the bug report. The main argument of the development team was that too many programs do not properly restore their data after being stopped. Hence, the development team decided that it was better to suppress the feature instead of leaving something that works half of the time. Many users were angry about it and preferred something not perfect to nothing. The development team did not change its mind.
